Question

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters. Find the approximate diameter of the flower. Use 3.14 for pie. Round to the nearest hundredth if necessary.

Answer 1

Given:

The worlds largest flower, the Rafflesia, has a circumference of 286 centimeters.

To find:

The diameter of the flower.

Solution:

We know that, the circumference of a circle is:

`C=2\pi r`

Where, r is the radius.

`C=(2r)\pi`

`C=d\pi`
`[\because 2r=d]`

Where, d is the diameter.

Putting
`C=286, \pi=3.14` in the above formula, we get

`286=d(3.14)`

`(286)/(3.14)=d`

`91.0828=d`

`d\approx 91.08`

Therefore, the diameter of the flower is about 91.08 centimeters.
